Results (1) The forward and reverse subtracted cDNA libraries of different metastastic potential large cell lung cancer cell lines were successfully constructed;(2) With blue-white colony and dot blot, 307 positive clones in the forward subtracted library and 78 positive clones in the reverse subtracted library were obtained;(3) 55 clones were successfully sequenced in the forward subtracted library. Homolog analysis confirmed 23 differential expression segments, which were similar to the human genes already known, including NME2, NPM1, MT 2A, HSPE1, TAFIA, EPRS, PX19 and EIF3S9 et al;(4) 31 clones were successfully sequenced in the reverse subtracted library. Homolog analysis confirmed 16 differentially expressed segments. 15 of them were similar to the human genes already known, including ANXA2, TUBB, PKN2, GNAS, EEF1A1, SSR2 and RPLPO et al. Only one segment had partial homology to known human genes. This segment was supposed to be the new EST segments which might not have been cloned.

Furtherly, the process design rules and methods in process station layout of multi-station progressive die as well as the methods of decompounding and compounding process and the expression method of the process station layout are concluded and summarized, and then the rule library and case library of process station layout are built. Designing the process station layout rapidly is carried out based on rules and cases. At last the rapid design function of process station layout is validated through simulating the rapid designing layout system of multi-station progressive die on Pro/E 3D platform.
